Product Description

         Twisted tube is a kind of enhanced heat transfer tubes that firstly presented by Swedish Alards Company, and then improved by the USA’ Koch Heat Transfer Company, LP.

      The structure feature of twisted tube is that every cross section is an oval, when when assembled into heat exchangers they exchanger they can be mixed bundles (that is, the mix of twisted tubes and bare tubes), and also can be a pure twisted tube bundle.

Enhanced heat transfer principles of twisted tube

     The unique structure of twisted tube can make the flow in tube pass and shell pass in the spiral motion at the same time, by this way it enhanced the turbulent intensity. The heat transfer coefficient of the twisted tube is 40% higher than the normal one, but the pressure drop is almost the same.
